Gitlab CI changes, and trigger flow need to be reconsider

on gitlab ci, automatic job triggering is not working as expected. Following items need to be redesign

• BUILD_VERSION support for addons iteratively
• changes need to be iterative, but does not work now
• it is running only for the branch itself, we need to find the solution for master
• needs may not be required each time, if we change only one add-on, job should start from that stage
  • if nodejs has changes, no need to build java but need to build gradle because nodejs image changes.
• need to build everything if .gitlab-ci.yml is changed
